Attorney General Jerry Brown is not revealing details of the arrest, his office said, but it comes soon after he revealed that pharmacy records show the actor got thousands of dangerous pills from dozens of doctors in the past year.

The person arrested was not directly connected to Haim but is suspected to be part of the drug ring, Brown spokeswoman Christine Gasparac said.

Haim, who starred in "The Lost Boys" and several other big 1980s movies before battling financial and drug problems for decades, was found dead Wednesday. The 38-year-old had flu-like symptoms in the days before his death, including a 101-degree fever. A doctor checked him Tuesday and ordered bed rest.

"Corey Haim's death is yet another tragedy linked to the growing problem of prescription-drug abuse," Brown said in a news release. "This problem is increasingly linked to criminal organizations, like the illegal and massive prescription-drug ring under investigation. It's a serious public health problem."

The investigation has uncovered more than 4,500 to 5,000 fraudulent prescriptions linked to the fraud ring in Southern California, according to a news release.
